Specification of Letters Patent.

"Patented Feb. 1, 1921.

Application filed October 4, 1919. Serial No. 338,412;

To all whom it may concern Be it known that I, THOMASJANSEN, a

citizen of the United States, and a resident of the city of New York,borough of Manhattan, in the county and State of New York, have inventeda new and Improved Adjustable Belt, of which the following is *belt isto provide one having peculiarly housed resilient members, stop meansbeing provided to prevent the over-stretching of said resilient members.7

Another object of the invention is to provide a belt construction, theseveral parts of which are so connected as to provide for completeseparation thereof for repair, interchange, or the like.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to theaccompanying drawings, in which like reference characters designate thesame parts in the several views, and in which- Figure 1 is a plan viewof one of my improved belts, parts being broken away on the line 1--1 ofFig. 2,

Fig. 2 is a vertical longitudinal section along the broken line 22 ofFig. 1.

Referring now more specifically to the drawings I show at 10 an innerbacking strip adjacent tothe opposite free ends of which are attached apair of keepers 11 or loops through which the other parts of the beltare guided. At the extreme ends of the backing strip 10 are fixed a pairof loops l2 constituting stop members. The central portion of the backinstrip is provided with a plurality of space anchor members 13 similar tothe well known head and socket snap fasteners. The head and shankportions of these fasteners are fixed permanently to the strip 10. a

Outside of, substantially parallel to, and practically coextensive inlength with the backing strip is an outer facing strip 14 the centralportlo'n of which is provided with as many-socket members 15 as thereare headed shank members 13 and with which they severally cooperate .forthe dual purpose first of securing the facing strip to the backing stripat the center, and secondl 'to establish anchor points for any suitalenumber of plates 16 to which resilient members 17 are connected. Theseresilient members are shown in the form of coil springs and have theirinner ends attached in holes 18 of the plates 16 while their outer endsare connected in similar holes 19 of movable plates or slides 20. Asindicated I provide two springs 17 for each pair of plates 16 and 20,but obviously the number might be greater or less as desired and insteadof using two plates 16 with a corresponding multiplicity of springs itmay be preferred in some instance to use only one spring or pair ofspringsattached to a single plate 16.

The remaining portion of the belt comprises in the main two straps 21and 22 which, as 1s also true of the backing and facing strips, may bemade of leather or any other suitable strong, tough, flexible material,either elastic or non-elastic as maybe deemed most expedient. Thesestraps are each provided with a looped end 23' threaded through a slot24 of a slide 20 and after passing through the stop loo 12 is adapted tobe secured to the interme iate portion of the strap by means of anysuitable separable fastener, 01 its equivalent, such as head and socketmembers 25 and 26 respectively to thereby vary the effective length ofthe strap so adjusted.v Obviously the slot 24 and the stop slide 12 arelarge enough to permit the snap member 25 to pass through, and whenthemembers 25 and 26 are snapped together the looped end of the strap is offixed length;

This description of the means for attaching either strap will beunderstood as being applicable to both straps 21 and 22.

The elastic members 17 and the anchorage or connection means thereforare all arranged along the outer face of the backing strip 10 and arecovered or faced completely by means of the facing strip 14. The guideloops or keepers 11 are large enough to permit the free longitudinalmovement of the.

looped end portions 23 and the slides 20 therethrough, the movementbeing outward while the slides approach the stops 12 which serve tolimit the extent of movement of the slides at all times irrespective ofthe length of the belt straps or the adjustment at the fasteners and 26.Consequently While the springs 17 provide ample elongation of the beltfor the utmost comfort to the wearer it is impossible to strain oroverstretchthe springs because of the slides coming into contact withthe stops. When the belt is relieved of the maximum tension that maythus be put uponit the elastic members serve naturally to return theslides toward the center of the structure. Any suitable buckle 27 may beprovided to detachably connect the loose ends of, the straps 21 and 22for the usual purposes.

'I claim:

1. In a belt of the nature set forth, the combination of a backingstrip, a facing strip extending along the backing strip and having itsend portions spaced therefrom, means at the middle portions of thestrips to detachably secure them together, a pair of straps having theirends located 7 in the spaces between the backing and facing strips, andmeans to secure the straps in the spaces aforesaid, the last mentionedmeans including separable fasteners and plates constituting the meansfor securing the two strips together.

2. In a belt of the class set forth, the combination with backing andfacing strips, head and socket means to secure these strips detachablytogether andwith the end portions thereof spaced from each other, a pairof straps, at least one of the straps having a looped end located withinthe space aforesaid and movable lengthwise thereof, anchorage means forsaid looped end, and elastic means cooperating with the anchorage meansand said looped end of the strap to serve as an attachment between thelooped end and the anchorage means.

3. In a belt of the class set forth, the combination of a backing strip,a facing strip extending therealong, means to fasten these stripstogether leaving a space between the ends thereof, a pair of straps, atleast one of which has a looped end located and movablelongitudinally'in the space aforesaid, a slide attached to said loopedend, a plate held in place by the means for attaching the strips to eachother, elastic connecting means between the plate and the slide, andpositive stop means carried by the end of the backing strip andcooperating with said slide to limit the stretch of the elastic means,

substantially as set forth.
